This invention relates to air flow control valves, particularly for useinassociation with air outlet devices having two separate 'setsor airoutlet openings, and has for its general object-to providea simple,practical 'valvewh'ich, merely by rotative adjustments'of asingle'"element thereof, may be rendered effective to"completely close theopenings of both sets against-any flow-of air therethrough; to' pa'rtlyclose the openings of either set and simultaneously to '-partly 'openthe openings of the other set-to permit-some flow of air through theopenings of-both-sets;- to completely close the openings of one set andsimultaneously to partly open' the openings of the other'set to denyall-fiow tlirough oneset and to permit a certain amount offlow throughthe other set; or to completely close :the openings of either setand tofully open the openingsof the-other set to completely deny flow ofairthrough the openingsof either set and topermitfullflow of airthrough theopenings of the otherset.

With the foregoing general object in view; the invention consists in avalve for 'the purposes stated embodying the novel features ofconstruction, combination and arrange-ment of partsas will behereinafter more fully d'escribed, illustrated in the accompanyingdrawings and defined in. the appended claims.

In the accompanying drawings, wherein like characters of referenceden'ote corresponding parts in related views:

-' Figure 1 is a central, longitudinal section through an air outletdevice and a control valve therefor constructed in accordancewith onepractical embodimentof the invention.

"Figure 2 is asectionon the line 2- 2 ofEigl 1, omitting the airdeflector elements shown in Fi 1.

"Figure 3 is a View similar to Fig. l illustrating an alternative formof air outlet'device andcontrol valve therefor, the section: beingtaken: approximately on the line 3+3 of Fig; 4; and

Figure 4 is a section on the line L -4.01 Fig. 3. Referring to thedrawings indetailg flrst with particular reference to-the form oftheinvention illustrated in Figs. 1 and 2, l0 designates a supply ductfor cooled or heated, fresh" or treated'air to be supplied toan-enclosure; and l l designates a circular opening in. a wall ll 2*ofsaid duct for outlet of air therefrom.

Suitably secured to the duct FWBJII iI Ziin covering relationship to theopening ll therein; is a fiat, circular plate l3, and in this plateare'inner and outer, annular, concentric rows of air: outlet openingsl4- and I5, respectively, which are alined with the opening it foroutlet of air from the duct 10.

Extending through a central opening in the plate 13 is an open-endedtube Hi the inlet'end of which is open to the atmosphere and the outletend of which is'disposed in advance of said plate 13, while fastened tosaidplate I 3 at the outer side thereof in surrounding relationship tothe inner annular row ofopenings M therein is a funnel-like airdeflecting element H for deflecting air'flowing from the duct ll]through said'inner row of openings 14 toward the outlet end of said tubei Sto induce a flow of atmospheric air'therethrough for intermixturewith the air discharged through said openings I i. Pr'eferably'a secondair deflector element iii'is providecl'to effect outward deflection ofair' flowing from the'duct Hi through the outerann'ular row of openingsl5, this deflector element l8 being, for example, in the form of aflared ring-like plate carried by the plate l3 and lying in advance ofthe openings l5. --Superimposed upon the plate !3 and suitably mountedfor rotation with respect thereto, as, for example, by having its outermarginal portion confined between said-plate l3 and the duct wall Handits'innenmarginal portion confinedbetween said plate It and aflangedring l8 fastened to and surrounding the tube his a valve diskillwhich also has therein inner and outer, annular, concentric rows ofopenings 2! and 22, respectively, for alinement with and disalinementfrom the openings 14 and 15, respectively, by rotation of said disk.

iiAny' suitable means such as the handle designated as 23-may beprovided for rotating the disk 2.9; 1 In any eventpthe arrangement ofthe openings' M; I 5; 2 l and: 2 ll: is such thatbyrotating saiddisktoonepositi'on;allof the openings I l and I5 may-be closed; byrotating said'disk to another position the openings it may be completelyclosed' and the openings l5 completely opened; by rotating: said disk toanother position the openingsv I5lmaybe completely closedand theopenings? 1'4- completelyopened; by rotating said disk to anotherposition the openings It may be completely closed and the openings 15partly opened any desired amounts; and by rotating saiddisk 'tootherintermediate positions the openings of either row may be partly openedany "desired amounts and the-openings of the other rowpar'tly closedequal amounts.

-More.'particularly, :thestated arrangement of the openings l4, l5, 2 Iand 22, as specifically illustrated in the: present instance, is asfollows: Therezare an equal number of. openings in each row of both theplate l3 and the valve disk 20; all of the openings are of the sameangular length; the openings of the two rows in the disk 20 areangularly alined; the openings of the two rows in the plate B areangularly disalined by amounts approximately equal to the angularlengths of said openings, and there are closed portions between adjacentopenings in each row approximately twice as long, angularly, as theopenings. It follows, therefore, that the disk 20 may be rotated to aposition to fully aline its Openings 2| with the plate openings l4 andsimultaneously to fully disaline its openings 22 from the plate openingsi so that all flow of air from the duct II] will be through the innerrows of openings l4, 2|; that said disk may be rotated to anotherposition to fully aline its openings 22 with the openings andsimultaneously to fully disaline its openings 2| from the openings |4-so that all air flow from the duct ID will be through the outer rows ofopenings I5, 22; that said disk may be rotated to an infinite number ofintermediate positions to partly aline its openings |4, |5 with theopenings 2|, 22, respectively, so that any desired proportion of thetotal volume of air discharged from the duct may be caused to flowthrough the openings l4, 2| and the remainder through the openings I5,22; that said disk may be rotated to completely disaline the openingsl4, 2| and simultaneously to partly aline the openings I5, 22 anydesired amount to deny all flow through the openings [4, 2| and topermit any desired amount of flow through the openings I5, 22; and thatsaid disk may be rotated to still another position to disaline all ofits openings from the openings in the plate l3 to cut off all flow ofair from the duct Iii.

Obviously, the specific arrangement of the openings l4, l5, 2| and 22shown and described may be varied considerably without changing thedescribed mode of operation of the valve. For example, the openings ofeither row in either the plate i3 or the valve disk may be displacedangularly relative to the openings of the other row therein any desiredamounts and if the openings in the corresponding row in the other ofsaid plate l3 or said valve disk are displaced angularly equal amountsrelative to the openings of the other row therein the mode of operationwill be the same as described for the arrangement actually shown.

Air deflector elements 24 may be provided to deflect air from the ductIi] through the openings I5 and I4 and any air that is permitted to flowthrough the openings I5 will be deflected outwardly by the deflectorelement 18, while any air that is permitted to flow through the openingsM will be deflected inwardly toward the outlet end of the tube It toinduce a flow of atmospheric air therethrough for intermixture with theair discharged through the openings M. In this connection, for a fullerexplanation of the general arrangement shown in Figs. 1 and 2, attentionis invited to our prior application, Serial No. 498,843, filed August16, 1943, now Patent Number 2,41 ,266 granted April 1, 1947, thisgeneral arrangement being shown in the present instance merely for thepurpose of illustrating one utility of the present valve.

Referring now particularly to the form of the invention illustrated inFigs. 3 and 4 of the drawings, l0- designates a cylindrical neck forconnection with an air supply duct, l3 designates a wall closing theoutlet end of said neck, and 2|] designates a cap-like valve coveringthe outlet end portion of said neck for controlling flow of airtherefrom.

In the end wall l3 is an annular row of air outlet openings l4, while inthe side wall of said neck is an annular row of air outlet openings IS.The valve 20 includes an end wall 25 and a side wall 26 and in saidwalls are annular rows of openings 2 land 22 respectively, for alinementwith and disalinement from the openings l4- and I5 respectively, byrotation of said valve relative to said neck. In this connection, thearrangement of said openings I4, I5 2 l and 22 is generally the same asdescribed in connection with the Figs. 1 and 2 form of the inventionand, in any event, is such that by rotating the valve 20 to oneposition, all of the openings M l5 may be closed; by rotating said valveto another position the openings i l may be completely closed and theopenings |5 completely opened; by rotating said valve to anotherposition the openings l5 may be completely closed and the openings I lcompletely opened; by rotating said valve to another position theopenings l4 may be completely closed and the openings i5 opened anydesired amounts; by rotating said valve to another position the openingsl5 may be completely closed and the openings H opened any desiredamounts; and by rotating said valve to intermediate positions theopenings of both rows may be partly opened.

The valve 20 may be mounted on the neck It in any suitable manner forrotation relative thereto as, for example, by means of a rivet, bolt orthe like 21 extending centrally through the walls l3 and 25. Moreover,any suitable means, such as the fixed pointer indicated at 23, may beprovided for cooperation with suitable index means on the valve 2i!" toindicate the relationship of the openings 2| to the openings l4 fordifferent rotated positions of said valve 20*. Furthermore, any suitableair deflecting means such as the wall indicated at I8 may be provided tocause air discharged through the openings l5, 22 to flow in any desireddirection from the device and any other suitable air deflecting means,such as the walls 23 projecting from the wall 25 in surroundingrelationship to the openings 2|, may be provided to cause air dischargedthrough the openings I l 2 to flow in any desired direction from thedevice. In short, Figs. 3 and 4 illustrate the application of a valve,having the characteristics of the valve illustrated in Figs. 1 and 2, toa device of the character shown and described in our copendingapplication, serial No. 498,842, filed August 16, 1943. 'Or, statedanother way, the valve arrangement shown in Figs. 3 and 4 is essentiallythe same as the valve arrangement shown in Figs. 1 and 2, except thatthere are a few number of openings in each row and except that the valveis in the form of a cap rather than in the form of a fiat disk.

The end Walls 13 and 25 may be flat or they may be of conical form, asshown.

Without further description it is thought that the features andadvantages of the invention will be readily apparent to those skilled inthe art, and it will of course be understood that changes in the form,proportion and minor details of construction may be resorted to, withoutdeparting from the spirit of the invention and scope of the appendedclaims.
